We describe the wide and rapid wavelength tuning of a continuous-wave master-oscillator power-amplifier system consisting of a semiconductor-amplifier-based oscillator and an ytterbium (Yb)-doped fiber amplifier. The oscillator utilizes an acoustooptic tunable filter and an intracavity etalon to achieve wavelength tuning of 36 nm in 5 ms. The 50-mW output from the master oscillator was amplified to over 9 W in an Yb-doped fiber amplifier.
